Brandt's cormorant (*Urile penicillatus*) is a marine bird native to North America's Pacific coast. It features glossy black plumage, a striking blue throat patch during breeding, and a long, slender neck. Skilled divers, they hunt fish underwater using powerful strokes. They nest in colonies on rocky cliffs and islands, often alongside other seabirds. Adapted to coastal life, Brandt's cormorants rely on upwelling currents for food. Their populations fluctuate based on ocean conditions, particularly El Niño events. These social birds communicate through vocalizations and displays, strengthening pair bonds. Conservation efforts focus on habitat protection and monitoring environmental changes.
